To all whom it may concern:

Be it known that I, Fnnnnnioir SCHNEIDER,

a citizen of the United-States, and a resident ofSeattle, in the countyof King and State of Washington, have invented certain new and usefulImprovements in In formal-Combustion Engines, of which the following isa full, true, and exact specific tion.

My invention relates to improvements in internal combustion engines andhas for its principal object to generally improve upon and simplifycombustion engine construction by eliminating'all valve springs andpuppet valves; by providing a cylindrical rotary valve which maybepositively geared t9 the crank shaft of the engine and which serves allthe cylinders of an engine. A. further advantage of my device lies inthe fact that the admission of gas and exhaust from the cylinders ispositively timed at the time of construction of the engine., Stillanother advantage lies in the arrangement for oiling the valve and itsmoving parts. It is a well known fact that much. of the combustion.engine troubles lie in faulty construction or operation of the valveswhich are generally quite complicated and require fine adjustments.

With my improved valve, there is a mini mum of noise, shock and frictionas all valve motion is rotary, which will give a very quiet operation ofthe engine.

Other objects will appear as the invention is more fully explained inthe following specification, illustrated in the accompany ing drawingsand pointed out in the appended claims.

In the drawings, Figure 1 is a plan of my improved engine with partsbroken away. Fig. 2 is a sectional elevation along line a'm. Fig. 3 isan enlarged cross sectional view of the engine valve taken through thepacking ring groove. Fig. 4: is a longitudinal sectional elevation ofthe valve showing a port and a packing ring.

Referring more particularly to the drawings, numeral 1 indicates themain cylinder casting of a four cylinder internal combustion engine- 2are cylinder heads. Pistons 3 operate in cylinders 2 in the usual mannerand are connected to a crank shaft 4: by connecting rods 5. A crank case6 completes the standard skeleton of an ord1- nary engine. The valvecasing consistsof a base portion '2' which is integral with or attachedto the cylinders, a cover 8 which is lntegral with or' attached to thecylinder cap 2. The joint between the two parts of;

the valve casing is preferably located so. that the ports on each sideof the valve are ontirely within one casing member: or the other. Withinthe valve casing is cylindrical opening in which a valve 9 fitsrevolubly. Intake ports 10 and exhaust ports 11 pass diametricallythrough valve 9 and register with intake and exhaust passages 1-2 and 13respect1vely, which communicate with the interior of the cylinder nearthe top. Ports 10 and 11 may be arranged spirally or otherwise aroundthe valve 9 so as to bring about any desired sequence of filling thecylinders and exhausting them. Passages 12 and 13 are continuations ofpassages 12 and 13 respectively, and connect into intake and exhaustmanifolds 14 and forced outof the valve by centrifugal force through oilholes 20 beneath packing rings 16 or elsewhere. The valve terminates atone end in a. shaft 21 which is positively geared to crank shaft 4 by achain 22 and sprockets 23 or otherwise. The charge of gas is sucked intothe cylinders as usual from the intake manifold when the intake port 10registers with passages 12 and 12,"

the valve being properly timed with respect to the piston in thecylinder. The exhaust port 11 comes into register with passages 13 and13 at the proper time for scavengering the cylinder" after combustionhas taken place, by firing in the usual mannor by spark plugs 24. Itwill be understood that the arrangement of ports gives the cylinders anydesired timing and'arran ement of firing the various cylinders,

T e ab sence of puppet valves, springs, cams and the like gives a verysimple enginewhlch will be easy running and noiseless.

1; While I haveshown a particular form of {$1 'embodiment of myinvention, I am aware that many minor changes therein will read ilysuggest themselves. to others skilled in the art, Without'departing fromthe spirit and scope of the invention, and I therefore 10 desire toavoid \being limited to the exact tension formed with a semicirculartrans verse depression, the last mentioned extension and depressionregistering With' the first mentioned extension and depression, thedepression forming a valve seat, the'exten sions, having inlet andoutlet ports which communicate with the cylinder body, a hol lowcylindrical valve rotatably mounted in the valve seat, said valve havingstraight ports extending therethrough adapted to so register atdetermined times with the inlet and outlet' ports, means'for supplyingthe insane? inlet port with a charge of explosive mixture, the valvehaving circumferential grooves each side the ports and oil portscommunicating with said grooves and the interior of the valve, packingrings seated in the grooves, and means for supplying the hollow valveWith a liquid lubricant.
